Name the action precisely
Cache and application data appear close together in many settings screens, which makes a vague instruction to clear the app risky. Decide what problem you are investigating and read the selected action before confirming it. If your only evidence is that one programme will not play, do not begin by assuming the whole application needs to be emptied. First note whether other items and menus still work.
Select the installed generation
Formuler’s current help page gives separate app-settings entries for MYTVOnline 2, 3 and 4 and lists the applicable model families. Open the entry that matches the application actually installed on the box. The menu label matters: selecting another player, a launcher or an older generation will not investigate the same application. Keep the version and exact error in your notes before making the change.
Protect the configuration before data removal
Treat a clear-data action as a separate decision from clearing cache. Make sure you can recover the account format and any local settings you need before taking an action that resets an application’s state. Avoid keeping recovery details in a public screenshot. If somebody is helping remotely, ask them to name the exact button and expected consequence rather than accepting an instruction to press whichever reset option appears first.
Check one outcome at a time
After the chosen action, reopen the same application and repeat the original test. Record whether the app opens, whether the account is accepted and whether the same item still fails. Repeating several resets in a row removes the evidence needed to learn which action mattered. A cache investigation concerns local software state; it does not verify content availability, account renewal or service compatibility on another model.
Questions, answered
Does this guide recommend clearing data first?
No. The manufacturer exposes both actions, but they are different choices. Preserve the information needed to recover the setup and investigate the exact symptom before deliberately resetting application data.
